As a member of the Hollywood 10, Dmytryk went to prison for refusing to answer questions about the Communist Party. Then he went back and named names after he got out of jail. What a yutz.
He was one of those guys who played a million bit parts on a zillion crappy TV shows, but his real claim to fame was as the dog catcher in the movie that stands as the all-time greatest source for Dead Pool candidates: Won Ton Ton, The Dog Who Saved Hollywood. Rent it tonight, and make a few lists.
